Date Thu, 01 Mar 2012 18:55:59 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3021?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13220243#comment-13220243

Suresh Srinivas commented on HDFS-3021:

Comments (some unrelated to the changes made by the patch):
# Can you please remove FSDatasetInterface.java BlockWriteStreams#close() throwing unnecessary
# Remove TimeoutException thrown from TestDatanodeVolumeFailureToleration#testVolumeConfig
# FSDataset.java - Remove unnecessary cast  (BlockVolumeChoosingPolicy<FSVolume>)ReflectionUtils
# DatanodeTestUtils - use dn.getFSDataset() instead of directly using dn.data

> Currently we have to cast FSVolumeInterface to FSVolume in FSDataset. Using generic type
could avoid it.
